Sit up

Movement: Lie on your back on the floor with your feet about shoulder width apart. You may find it easier to put your feet under something to hold them down. Lift your upper body, bending at the waist, until you’re sitting up vertically. Keep your arms at your sides, crossed in front of you, or behind your head, but do NOT attempt use your arms to pull yourself up. Do not raise your feet off of the ground. Smoothly lower your body back to the floor. Repeat.
